Limited Slip Diff

Ben that was me re the 964 RS and GT RS, are you saying the GTR is a better car than the GT3 RS ?
Need to check my diff now as i thought that all lsd had oil cooler, will check the build stickers the morrow, not changing it if it is not the case though £££

Where is my badge panel ??

Keeping WUF ?
Pretty sure i would be after getting all that bodywork done, do some miles in it. []

Ops. Sorry I read and didn't look at poster. No the gtr was terrible (in that way), gt3 felt so raw after it that I was amazed at your comment about how it felt like it was doing things for you.

I have the panel back, one of the black plastic inserts is missing but I have it now.

Whether I keep wuf or not long term is still very much in balance. That superlight 911 has made an impression on me that will not be forgotten, but short of having one built for me it's not an option at the moment and driving wuf in the meantime this summer is a very nice place to be.

I read a report of the 997 turbo, GT-R and BMW M3. The M3 wasn't in it really, and thought he GT-R was quicker round the track (one lap) than the 911 the driver said it cornered as if it was driving round a 50 pence piece. I'm assuming that this is because it is the electronics actually doing all the work rather than the driver's inputs and the car is shifting the power around hunting for the limits of grip. A technological marvel, but for me cars need to have a sensible blend of electronics to make the huge power available to the majority of the drivers who buy these cars, but not so much that it starts to take over. What's the point in driving if you're not doing the driving. The GT-R is a technological marvel - much like the Eurofighter (like how i've brought the two strands of this thread together?) - but like the Eurofighter, the computer does the driving for the driver who is basically relegated to a navigational aid - you could take out the driver and hook up the sat nav to the ECU and you have a car that could drive itself!

Scott, not forgetting the B should have a much greater range/endurance due to not needing a lift fan. Highly desirable I reckon for any Naval aircraft.

Can the Eurofighter airframe take a beefed up under carriage? If it can't and I suspect given it was never designed for cat'n'trap the answer is no then you are in to new airframes (reworked is not much different to new). Having said that though there are definite benefits to having commonality of engines, avionics, comms etc.

You're right Neil, the STOVL aircraft's performance is reduced by carrying all that STOVL kit around with it, which for most of the time is redundant and dead weight and takes up valuable space within the airframe. The Harrier was so much more of an elegant solution, but lacks of range and supersonic capability. Uprating the undercarriage and airframe on a Eurofighter is not so much of a technological problem, but by navalising the Eurofighter you're always going to end up with a huge compromise and the aircrafts performance and operability will be massively compromised - analogous to convertible cars - you're always compromising a car if you chop the roof off rather than designing it to be a convertible from the outset. Though in these times of austerity the financial benefit of a common platform may trump the actual aircraft's capabilities much to the dismay of the RN and its pilots.

Not stupid at all. Its only politicians who seem to think these things have to be done as multi-national efforts (Submarines such as Astute prove we certainly have the industrial capability to design and build world class big ticket equipment, the much more expensive Virgina class is arguably the only thing that can touch it). There is also this huge myth that the US is great at this sort of thing (efficient, on time and budget) and euroland is rubbish. Its my personal opinion but the previous administration here was in love with the US and US companies.

The French have managed to keep a remarkable level of independence in this area, there really is no argument as to why the UK couldn't also.

Unfortunately all military projects are politically driven. Its all about selling our kit abroad and getting access to overseas markets - there is no room for sentiment or ethics unfortunately. The arms business is huge and is a good slice of our export market and earns us a huge amount of money - and it is real money and badly needed. Not selling arms to these dodgy dictators sounds like a perfect policy from a humanitarian angle, but in the real world no responsible Prime Minister would have the courage to put the financial stability of this country at risk - we're basically bankrupt now, if we lost our arms exports without the ability to plug that gap with some other source of income then we'd be lining up behind Portugal, Ireland, Greece & Spain with cap in hand to the EU. It is a ridiculous and stupid world we live in - forced to reward the unworthy (bankers, financiers and premiership footballers), and deal with the devil (countries with lower ethical standards than we have).

Agree 100% Scott on all 3 counts. Trying to be all clever and 'ethical' in military equipment sales is a bit like crystal ball gazing trying to predict what will happen in 20 years time. Beyond not selling to nut jobs in the here and now I don't believe there is much one can do, so you either have such an industry or you don't. We have a similar fix with the finance industry, we either keep London as one of the best places in the world to do this business or we don't have a world class finance industry.

Back to Ben's car dilemma, personally I find the idea of a track special torsion bar 911 very exciting. However I don't think putting a more modern big engine into an old chassis is a great idea, it would be better to tune up one of the older motors as I think high revs and more peaky power delivery goes nicely with a lightweight finely balanced car. One could for example start with a 3.2 carrera, strip it out, LSD, bilsteins, ARB's, big brakes, RuF front and rear bumpers and mirrors, then rebuild the motor up into the 270 to 300 Bhp range. That would do very nicely thanks, should be pretty easy to get 250 Bhp/tonne.

 

[944Turbo]

Still way off topic but having been within 100m of a eurofighter doing a full re-heat take off, I can say that it is a very impressive thing, they don't need much runway

 

[surrey 944T]

its very unlikely to have one fitted, easy to find out do a racing start it will leave 2 black lines only if its got an lsd.
if its wet drop the clutch and see if you can hold a slide coming out a junction, = lsd, open diff = just the inside wheel will spin all the power away.

or you could jack it up as described.

 

[steves944]

Is there not just a way of looking at the casing and telling, rather than having to learn the history of aviation in the UK! ( Gotta admit though it is seriously interesting and informative.)

 

[Mike_Pollock]

Problem is the number is on the top!

Jack it up - both wheels - turn one and see if the which way the other turns - or bring it here and I'll have a look!

My cousin has an LSD box in his shed, do I really need one? and will it make a huge difference?

There is a difference to the way the car 'feels' with an LSD fitted but in terms of practical use the only times you ever really notice the difference are traction off the line and selling price/ease of sale.

Personally, and especially in a standard car I wouldn't be in a great hurry to change it.. but keep hold of it because they are rare as hens teeth!
